Princess Grace Hospital Center

The acoustic firm Tisseyre + Associés has developed a joint working methodology with the architect. Indeed, our 4D digital soundscape modeling tool in the future state of completion, the BIMAE®, is an essential work support for close collaboration with architects and urban planners at all stages of the project. The BIMAE® allows a joint study of the internal and external functions of the projects and the 3D visualization of the sound propagation at the foot, on the facade and around a building at any time of the day. Thus, we were able to anticipate, optimize and integrate the acoustic solutions within the architecture of the project.

Complete acoustic mission

Thanks to BIMAE®, we were able to carry out the sound impact study for the creation of new transport routes, land and air (via the helicopter) on the CHPG and its surroundings. As a result, we dimensioned and integrated the acoustic solutions into the architecture from the early stages of the design.

Management of site vibro-acoustic issues

This site is particularly complex because of its embedding in urban planning and the construction on rock. It is therefore a question of being able to predict the sound and vibration impacts of the construction site on the hospital in its operational state and on the surrounding areas in order to deploy several solutions, thanks to BIMAE®:

• Adaptation of site techniques (favor drilling over continuous percussion);
• Projected sound maps of the site in order to anticipate the solutions and the time management of the tasks;
• Installation of measurement stations to control noise levels.

Tailor-made vibration solutions

CHUs are buildings that are particularly sensitive to vibrations since MRIs must not be subjected to any vibration at the risk of malfunctioning. We have adopted 2 types of tailor-made vibration treatment:

• Treatment at source: special rock wool underlayment under the pavements to attenuate vibrations, choice of special joints for the pavements, etc.
• Receiver processing: structural impedance breaking solution to avoid amplification of suspended systems. The MRI slab is placed on freighted neoprene plates, which reduces the contact points and thus divides the vibration effects by 10.
